Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for handling functional alias in a conference event package in a wireless network by a server. The method includes detecting a group call associated with a group in the wireless network. Further, the method includes providing a SIP NOTIFY message comprising an ID of each member of a plurality of members of the group, and an IE indicating the functional alias bound by each member of the plurality of members with the group. Further, the method includes sending the SIP NOTIFY message to a client device corresponding to each member of the plurality of members of the group.

Abstract: Embodiments herein disclose formats for MCData messages and notifications, and methods for coding (encoding and decoding) MCData messages and notifications in a MCData communication system. The method includes generating, by a first UE, an encoded MCData message or notification comprising of signaling payload and data payload content related to one or more MCData user payloads. Further the method includes deriving, by a second UE, the actual MCData messages or notifications by decoding the received encoded MCData messages or notifications. The formats for MCData messages and MCData notifications optimize control headers and allow maximum user data size that can be carried in a single message over signalling, which aids in sending multiple user payloads in a single message.

Abstract: In an example embodiment of present disclosure, a method and apparatus to exchange an SSRC value between a client and a server for implicit floor requests are disclosed. In an embodiment, the exchange of the SSRC value between the client and the server for implicit floor requests is being done with Explicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in FMTP media attribute of Session Description Protocol (SDP). In an embodiment, exchange of the SSRC value between the client and the server for implicit floor requests is being done with Implicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in FMTP media attribute of SDP. In an embodiment, exchange of the SSRC value between the client and the server for implicit floor requests is being done with Implicit/Explicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in SSRC and FMTP media attribute of SDP.

Abstract: Optimal network resource consumption by dynamically controlling media bursts in Simultaneous PoC (Push-To-X (Push-To-Voice/Video/etc.) Over Cellular) calls. Embodiments disclosed herein relate to wireless communication networks, and more particularly to PoC calls performed using wireless communication networks. Embodiments herein disclose methods and systems for optimal network resource consumption by dynamically controlling media bursts, when a user is participating in simultaneous PoC sessions. Embodiments herein disclose methods and systems for optimal network resource consumption by enabling a user to selectively enable/disable multiple PoC sessions using MBCP “Activate” and “Deactivate” messages.
